[Please note that the actual contents of file have no reln with the query]
I need to get the count of minimum columns per line. i.e. in above case, it should come out to be 1 since the last line only has 1 column.
I tried following code:
Have 2 queries:
1 > Will this work !!!! ???
2 > The reason I myself cannot answer the 1st query is for the following errors:
line 3: minCount : command not found
line 4: wordCountPerLine : command not found
line 22: syntax error near unexpected token `('
line 22: ` for (i =0 ; i < NF ; i++)'
Please help out

The file is similar to the attached.
Thousands of columns, delimiter is tab, with many columns containing free text and space separated.

eg.Col1=10, Col6=5, Col8=1

while
while(1T) Tcl Built-In Commands while(1T)__________________________________________________________________________________________________________________________________________________NAME
while - Execute script repeatedly as long as a condition is met
SYNOPSIS
while test body
_________________________________________________________________DESCRIPTION
The while command evaluates test as an expression (in the same way that expr evaluates its argument). The value of the expression must a
proper boolean value; if it is a true value then body is executed by passing it to the Tcl interpreter. Once body has been executed then
test is evaluated again, and the process repeats until eventually test evaluates to a false boolean value. Continue commands may be exe-
cuted inside body to terminate the current iteration of the loop, and break commands may be executed inside body to cause immediate termi-
nation of the while command. The while command always returns an empty string.
Note: test should almost always be enclosed in braces. If not, variable substitutions will be made before the while command starts execut-
ing, which means that variable changes made by the loop body will not be considered in the expression. This is likely to result in an
infinite loop. If test is enclosed in braces, variable substitutions are delayed until the expression is evaluated (before each loop iter-
ation), so changes in the variables will be visible. For an example, try the following script with and without the braces around $x<10:
set x 0
while {$x<10} {
puts "x is $x"
incr x
}
EXAMPLE
Read lines from a channel until we get to the end of the stream, and print them out with a line-number prepended:
set lineCount 0
while {[gets $chan line] >= 0} {
puts "[incr lineCount]: $line"
}
